Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511820, here are decompositions:

31 + 33511789 = 33511820
103 + 33511717 = 33511820
127 + 33511693 = 33511820
151 + 33511669 = 33511820
193 + 33511627 = 33511820
211 + 33511609 = 33511820
271 + 33511549 = 33511820
313 + 33511507 = 33511820

Showing the first eight; more decompositions exist.
